Practice speaking with a cork in your mouth.
Many actors and voice actors do this exercise to increase clarity and diction, especially when it comes to something like Shakespeare.
By putting a cork between your teeth and speaking aloud you train your mouth to work extra hard to really pronounce every syllable, and the cork will also prevent your tongue from tripping you up on certain words.
- This exercise can tire your jaw, which will help you learn to relax it, but you shouldn’t do this for too long so you don’t get sore.
- You may also want to have a napkin with you as you produce a lot of saliva with this method.
